Lottery Winnings Gift Tax Simulator | Tax on Sharing Prize Money With Family
Simulate the Japanese gift tax owed when you share lottery winnings with family or friends, based on the annual basic exemption of 1.1 million yen and the general/special tax rate tables. See the tax and net amount for each recipient at a glance.
Lottery winnings themselves are tax-free in Japan under the Lottery Ticket Act (当せん金付証票法), but if the winner shares part of the prize with family or friends, the recipient may owe gift tax on the amount received. Use the tax rate tables and simulator below to estimate the gift tax for a given distribution.
General Tax Rate (for general gift property)
| Taxable amount after exemption | Rate | Deduction |
|---|---|---|
| 200万円以下 | 10% | ― |
| 300万円以下 | 15% | 10万円 |
| 400万円以下 | 20% | 25万円 |
| 600万円以下 | 30% | 65万円 |
| 1,000万円以下 | 40% | 125万円 |
| 1,500万円以下 | 45% | 175万円 |
| 3,000万円以下 | 50% | 250万円 |
| 3,000万円超 | 55% | 400万円 |
The general rate applies to gifts that do not qualify for the special rate, such as gifts to a spouse, siblings, or friends. Sharing lottery winnings with a spouse or friend typically falls under this rate.
Special Tax Rate (for special gift property)
| Taxable amount after exemption | Rate | Deduction |
|---|---|---|
| 200万円以下 | 10% | ― |
| 400万円以下 | 15% | 10万円 |
| 600万円以下 | 20% | 30万円 |
| 1,000万円以下 | 30% | 90万円 |
| 1,500万円以下 | 40% | 190万円 |
| 3,000万円以下 | 45% | 265万円 |
| 4,500万円以下 | 50% | 415万円 |
| 4,500万円超 | 55% | 640万円 |
The special rate applies to gifts from a lineal ascendant (parent or grandparent) to a lineal descendant aged 18 or older (child or grandchild), and results in a lower tax than the general rate for the same taxable amount.
* Japan's calendar-year gift tax includes a basic exemption of 1.1 million yen per recipient per year (Inheritance Tax Act, Articles 21-5 to 21-7). The simulator below applies the tax rate table to the amount remaining after this exemption is subtracted.
Simulate Gift Tax by Distribution Amount
Tips
- The 1.1 million yen basic exemption applies per recipient per year, so splitting a gift among more people reduces the taxable amount each person owes on.
- If the recipient is a child or grandchild aged 18 or older receiving from a parent or grandparent, the special rate applies and results in a lower tax than the general rate for the same amount.
- Spreading a gift across multiple calendar years lets you use the 1.1 million yen exemption again each year, which can reduce total tax versus a single lump-sum gift — though tax authorities may scrutinize gifts that look like a single gift artificially split up.
- If the resulting gift tax is high, it may be worth considering having the winner keep the winnings as their own asset and let it pass through inheritance later instead of gifting it now.
Frequently Asked Questions
Side Note — Why Winnings Are Tax-Free but Sharing Them Isn't
The reason lottery winnings are tax-exempt in Japan traces back to Article 13 of the Lottery Ticket Act, which explicitly exempts prize money from income tax and other national taxes. The idea is that ticket sale proceeds already fund local government contributions and public welfare programs, so taxing the winner's prize on top of that would amount to double taxation. As a result, as long as the winner keeps and uses the money themselves, no tax is ever levied.
The moment the winner hands part of the prize to a family member or friend, however, the picture changes. Legally, that act of "handing over" money is treated as a gift from the winner to the recipient, and gift tax is a completely separate tax that applies to any transfer of assets between individuals — regardless of where the money originally came from. In short, the Lottery Ticket Act's exemption applies only to the winner's own receipt of the prize; it does not extend to what happens afterward.
In practice, the tax treatment can shift depending on the circumstances — for example, if the ticket was purchased jointly under a family member's name, or if a group purchase and split were agreed upon in advance. Anyone considering distributing a large windfall should treat this simulator as a rough guide only, and consult a tax office or tax accountant based on their actual situation before deciding how to proceed.
